[media] ddbridge: remove unneeded check before dvb_unregister_device()

Author: Markus Elfring <elfring@users.sourceforge.net>

The dvb_unregister_device() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
